    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

solar panel efficacy in charging battery

It would work okay as a battery maintainer. It would take a month or so to fully charge a battery with one. It probably puts out something on the order of .05 amps. It should work out to .085 but solar panels don't quite meet the output using the usual formula since they don't always have optimal sunlight. A 10 or 20 watt panel would be better suited for charging and even then would take a good day to charge a battery fully.
 
A battery maintainer outputs 1.0 - 1.5 Amps. You'll want a larger panel as Billy Ricks stated, and you'll want to place the panel in the place where the most sunlight exists (out of doors, most likely) and then run the cables to the bike.
You would also want some type of regulator so you don't overcharge the battery.
 
They make some specifically for vehicle batteries to be used while camping.
